    • Gives people a chance to show case their work to millions of people
    • Winner of this context will go into all shipped CDs and downloaded images of 9.04
    • Audio, 1MB max, in ogg vorbis
    • Video, 2.5MB max, in ogg theora
    • Photo/Graphics, 0.5MB, PNG or JPG
    • Must be licensed Creative Commons Attribution Sharealike
    • Submissions due February 6th, 2009
  • UDS Jaunty Jackalop is next week at Google headquarters
    • UDS is where people talk about what will go into the next release
    • Currently there are about 145 blueprints, things that could get discussed
      • improving boot time seems like a real interesting one
    • obviously none of it is in stone
    • Keep your eyes open for ways to participate and see what is going to be going on
  • Adobe releases alpha 64 bit Flash for Linux
    • Not Ubuntu specific, but its a big deal with most Linux users
    • Till now, 64 bit users had to use nspluginwrapper
      • nspluginwrapper is compatibility plugin, meaning it enables you to use plugins on platforms they were not built for.
    • Crash stats from Mozilla show 25% of all Linux Firefox crashes are Flash related
    • To test it out on your system, uninstall the flash-nonfree package, drop the libflashplayer.so that you download from Adobe in your ~/.mozilla/plugins/
  • Handbrake gets a Linux GUI
    • almost the standard DVD ripping, multi-threaded, multi-platform, GPL
    • So far only Ubuntu binaries are available, hopefully more coming out soon
    • Previous attempted front-ends have been decent at best, hopefully this is better
  • Phoronix continues with its benchmarks: 64 bit Ubuntu 8.10 vs FreeBSD 7.1 vs OpenSolaris 2008.11
    • Tested with Ubuntu 8.10 final and beta releases of FreeBSD and OpenSolaris
    • All OSs left in their default configuration
    • Tests included MP3 encoding, compression, GPG, Java, etc
    • Ubuntu won out most of the time
    • Java did the best on OpenSolaris unsurprisingly
    • If need disk performance, OpenSolaris did the best
  • Phoronix does more tests: Fedora 10 vs Ubuntu 8.10 w/32 and 64 bit
    • Tests included OpenArena, Enemy Territory: Quake Wars, Gzip compression, MP3 encoding, Ogg encoding, Java, GPG, etc.
    • Performance difference between distros was neglible
    • Basically, go with whichever distro you are more comfortable with
  • CrunchBang Linux
    • Based off Ubuntu
    • Uses the OpenBox window manager, but allows you to run all your GNOME apps
    • Created from a minimal Ubuntu install and adding layers on top of it.
    • Default theme is cool, all black and white
    • Not supported by Canonical, but if you are comfortable with Ubuntu, CrunchBang should be pretty easy to use
  • Hardening the Linux Desktop
    • IBM tutorial that uses Ubuntu
    • Registration required
    • Shows to do the following things:
      • installing ClamAV
      • protection from rootkits
      • Setting up Firestarter as a firewall
      • backing up and restoring home directories
      • how to install the Ubuntu updates
      • password protecting the bootloader
  • Vibuntu 1.0: A Customized Version of Ubuntu for Visually Impaired Users
    • Remaster of Ubuntu 8.10 Live CD customised to the needs of blind and partially sighted users
    • Designed to boot from a live cd or USB memory stick
    • Logs you in automatically and then start up the Orca screen-reader
    • Full-screen magnification can then be activated with a simple keystroke.
  • Testing ads
    • We would like to buy a hi-def camcorder and some other equipment to make the podcasts better

      • You can always encrypt whole drives or partitions
      • But what if you just want to encrypt a folder in your home directory?
      • And don’t want to encrypt and decrypt continiously?
      • This new feature will encrypt a directory with your regular login/password and decrypt it whenever you login.
    • New Guest user session switching applet
      • Creates a temporary password-less user account with restricted privileges
      • it cannot access any regular user’s home directory,
      • cannot permanently store data.

    • Updated Network Manager
      • Managing 3G connection
      • no need to login to set up a connection
      • Managing PPP and PPPOE connections (which is used by lots of DSL providers)
    • Other interesting Intrepid news
      • Tomcat6 had been uploaded to intrepid and is waiting for testing.  It should be available for Intrepid
      • Current behavior when RAID fails is for the system to boot to a recovery console.
        • Server team is adding an option that would allow administrators to specify that the system should instead boot in the degraded RAID state.
        • This would allow systems with redundant disks to get back up and running without requiring human intervention.
  • Free IT Athens working with Clarke County School District to provide up to 2,000 computers to students and families who can afford them
    • Athens is about an hour NE of Atlanta
    • Very much needed in county where 80% of students qualify for free or reduced price lunches
    • Pilot program involved 130 used computers
    • 600 more to be refurbished in the fall
    • 1200 more next year
  • Empathy is a set reusable IM widgets, that could possibly replace Pidgin in Intrepid
    • Not meant to be cross-platform like pidgin
    • Has voice and video support
      • Some folks who tried it out said Empathy works flawlessly with Google Talk users.
    • Its uses the Telepathy framework in Gnome
      • Telepathy supports real-time unified IM, voice, and video communication over DBus
        • DBus is the way applications talk to each other
    • Can also use libpurple, the libraries the pidgin uses, for networks that aren’t implemented yet.
    • No final decision has been made yet!
  • How To Forge has a slick 2 page how to on installing openVZ on Ubuntu Server. Talking about more virtualization, this is an awesome way to run multiple environments.
    • We spend lots of time talking about vmware and virtualbox (like last week), don’t forget to try out openVZ
    • openVZ is in the repos
    • Ubuntu Florida LoCo website ran on OpenVZ until Aug, and will soon be running there again.
  • Ubuntu Love Day Manila 2008 – On August 23, 2008, the Ubuntu Philippines LoCo, with University of the Philippines Department of Computer Science and Engineering, will hold an event for sharing experiences, learning, and meeting fellow enthusiasts
    • Invited 6 resource persons to share their experiences with Ubuntu in different areas of interest:
      • The Ubuntu 30 day challenge – Aileen Apolo (Google)
      • Ubuntu on virtualization and integrating to a Windows Network – Wallen Tan
      • Ubuntu: Saving lives (and then some) – Charo Nuguid
      • Choice is Good! Welcome to the Exciting, Productive and Wacky World of Ubuntu Derivatives – members of UP Linux Users’ Group (UnPLUG)
      • Ubuntu and the OLPC XO-1 – Rowen Remis Iral (OLPCPH)
      • Kubuntu & KDE: Contributing to an International Software Project – Juan Carlos Torres (KDE Project)
  • Ubuntu attracts the lion’s share of LinuxWorld’s smaller crowds!
    • Each Ubuntu presentation and training session throughout the three days of LinuxWorld was heavily attended, especially compared to similar sessions elsewhere where relatively few attended.
    • Even though attendance was a bit sparse during this year’s LinuxWorld Conference & Expo when compared to previous years, the Canonical booth — where the latest Ubuntu Linux software was being shown off — still managed to draw a crowd.
    • Cancellation of Ubuntu Live might been a good thing
    • LinuxWorld had people who use many different distros, Ubuntu got exposed to them, not a self-selected group

Ubuntu Podcast Episode #4

without comments

We recorded the podcast from the IBM conference center in Atlanta on 8/9/2008. Jim, Josh, and Nick discuss the upcoming Atlanta Linux Fest 2008 as well as what’s new in the Ubuntu community. There is a high res .avi download encoded in xvid, as well as the streaming flash, .mp3 and .ogg audio formats. I will try to post a lower resolution video for those with lower bandwidth, but I wanted to get this out.

Show Notes

  • Atlanta Linux Fest plans
    • Multimedia on Linux
    • Dual-Boot your College PC and make it more useful!
    • Gaming
    • Symphony
    • Lunch: Pizza
    • Hands-on:
      • breakout sessions
      • one-on-one trouble shooting.
  • Ubuntu on subnotebooks
    • At OSCON, Canonical had Ubuntu running on Atom-based subnotebook.
      • Atom is Intel’s line of CPUs for ultra-mobile PCs, smart phones.
      • The CPUs are smaller than a penny.
      • Notebooks ran Ubuntu Netbook Remix
      • Touchscreens are becoming prevalent, so the finger-friendly UIs will be interesting

Big week of applications going into the repos

  • IBM partnering with Canonical (see here and here) to make IBM Open Collaboration Client Solution (OCCS) availabe the repos.
    • Notes is their email platform
    • Smyphony is a fork of Open Office.
  • Alfresco – enterprise content management system being put into partner repos. 100% open source.
    • There are two editions: Alfresco Enterprise Edition and Alfresco Labs
    • The repos will have Alfresco Labs, which is the bleeding edge, GPL
    • Alfresco EE is certified on various systems, has professional support, partners and consultants can provide services, subscription service
  • Ubuntu restaurant
    • vegetables only restaurant in California.
    • Website features a video interview with Nelson Mandela and has an Ubuntu logo on it.
    • The video is also included in the Examples folder of all Ubuntu desktop installations
  • Ubuntu has become “noobified”? It’s a dated article, but still relevant.
    • Somehow, being easy to use is bad: “but Ubuntu has become so watered down as a Linux distribution that I can only classify it as having been completely n00bified”
    • He is used to Fedora: ” I use it 99% of the time while at the University (the other 1% is with Windows), and have had a Fedora Linux server sitting in my office for three and a half years.”

Ubuntu Podcast Episode #3

without comments

Josh is on vacation this week, down in Destin, probably having way too much fun.

Show Notes

  • Alpha 3 released, Alpha 4 comes out August 14th
  • Mark Shuttleworth talk at OSCON got huge coverage: basically, Mark throws down the gauntlet: Make Desktop Linux Better than Apple
    • In 2 years, can the Linux desktop go from stable, robust, and not so pretty…to just blowing by Apple?
    • Journalists and bloggers are asking: Is it possible? Apple controls the whole stack, Linux/Ubuntu can’t
    • Journalists and bloggers are asking: Is it possible without someone taking charge?
    • Will be interesting to see what the ArtWork Team can come up with.
    • 8.04 was supposed to have some cool new themes, but it got pushed.
  • Ultamatix, successor to Automatix released – it basically installs applications and commonly-used audio and video codecs.
    • Some of the applications might not be free or might having licensing issues
    • Or sometimes no one has gotten around to putting them into the repositories yet.
    • AX was very controversial. When it started out, made it easier for new Ubuntu users. But it would tended to cause people lots of pain eventually during upgrades.
      • Matt Zimmerman, Ubuntu CTO, said “I cannot recommend the use of this program, and systems where it has been used cannot be supported with a clean and official upgrade path.”
      • Matthew Garrett, who was on the Ubuntu Technical Board at the time, took a look at AX: “In its current form Automatix is actively dangerous to systems – ranging from damage to small items of user configuration, through removing user-installed packages without adequate prompting or warning and up to the (small but existing) potential to leave a system in an unbootable state.”
      • They were asked to work with Ubuntu developers, but not much progress was made.
      • Eventually Automatix got sold off and there was no release for 8.04
    • Ultamatix – Not done by the AX people
    • Ultamatix creator says he tried to fix the problems that Automatix had -
    • Its been pointed out that Ultimatix uses apt force-yes options:
      • from man pages of force-yes: “This is a dangerous option that will cause apt to continue without prompting if it is doing something potentially harmful. It should not be used except in very special situations. Using force-yes can potentially destroy your system!”
    • It seems like when people are reviewing it, they are not looking under the hood. Specifically, a certain linux.com article which was a rave review of Ultamatix.
  • Linux pre-installed on 2.8% of machines sold in the UK since Vista has been released.
    • Might not seem like a big deal, but its big news since it jumped from .1%
  • Full Circle Magazine #15 is out.
    • Pretty cool magazine, kinda like Linux Format
    • Only available online in PDF format
    • First issue came out June 2007
      • The Ins and Outs of Directories.
      • How-To : Separate Home Partition, Create Your Own Server Part 7, Using GIMP Part 4 and GRUB 101.
      • MOTU Interview – Mathias Gug from Server Team
      • Also gets translated into several languages
  • Launchpad 2.0 Out – Its where a lot of Ubuntu-related projects are hosted.
    • What is LP?
      • Hosting service for open source projects
        • share code
        • file bugs
        • translations
        • New 2.0 release include:
          • APIs to access LP data without going through the web interface
          • code reviews
          • mailing lists
          • integration with bugzilla and trac, which are pretty common and widely used apps for filing bugs
    • Some other big name projects like MySQL and Zope
    • Source code for it has been closed so far, at OSCON, Mark Shuttleworth said code would be released in the next 12 months.
    • Good thing of having only one Launchpad is being able to file bugs properly. Say someone files a bug in Ubuntu that is really in MySQL, its easy to assign the bug over to MySQL.
    • Once open sourced, you’ll see lots of different Launchpads pop up and the collaborative nature will become tougher.
  • Ardour screencasts – Ubuntu UK team is in the process of doing a 13-part series on mixing a podcast with Ardour:
    • So far discussed:
      • setting up environment
      • arranging tracks
      • adding music, cool effects like fading in and out
      • compression
      • filters

If you have problems listening to the ogg or mp3 on the webpage, please try downloading it.

    • Florida team will be joining us
  • Ubuntu Eee SD Cards available
    • $50
    • 4GB SD card
    • Nothing to install
    • Just select to boot from SD card
  • New community driven QA team: For quite a while Canonical has largely driven QA efforts in Ubuntu, and the community can and should step up in this area. On a high level, the Ubuntu QA team is about coordination and developments, focused on developing tools, policies, and practices for ensuring Ubuntu’s quality as a distribution as well as providing general advice, oversight, and leadership of QA activities within the Ubuntu project.
    • To get involved, join the Bug Squad. Members:
      • assign bugs to packages
      • ensure that bug reports are complete
      • find duplicate bug reports
      • recreate bugs and forward bugs to their upstream authors.
      • All of these activities help the bug get fixed and subsequently
        making Ubuntu even better.
    • Also, join the Testing Team:
      • Structured testing of packages and ISO images.
      • Aim to detect as many bugs and issues as possible before CDs are
        released to the general public.
  • Ubuntu 8.10 Intrepid Ibex Alpha 3 coming
    • Expected to be released Thursday, July 24th.
  • Ubuntu Massachusetts LoCo
    • Fourth “Exploration Ubuntu” event to demonstrate what this easy-to-use
      Linux system has to offer.
    • Saturday August 2nd at the MIT Media Lab

Ubuntu blogsphere Trends:

  • Configuring Linux Terminal to work as a transparent wallpaper:
    • Uses devilspie is a non-gui utility that lets you make applications start in
      specified workplaces, in specified sizes and placements, minimized or
      maximized and much more based on simple config files.
  • Installing new fonts easily
  • Dell is upgrading Ubuntu machines to ship with 8.04 LTS.
    • Wonder if they will release 8.04 ISO like they had for 7.10.
    • Dell does have its own PPA (Personal Package Archive) on Launchpad and it does get added to package source lists if you buy an Ubuntu Dell machine.
  • Intel Snubs Microsoft, offers Linux certification: Intel’s enthusiasm for open source is gathering speed: now it is endorsing professional Linux certifications, snubbing the old Microsoft certification program.
    • Attendees at the Intel Developer Forum get discounts for taking open source exams from Linux Professional Institute.
    • No such deal for Microsoft certifications.
    • At one of last years Intel Developer Forum, Intel embraced Linux, instead of Microsoft, for its mobile Internet devices
    • At another Intel Developer Forum last year, Mark Shuttleworth gave one of the keynote speeches.
    • Intel sponsors the Moblin project for developing a standardised open source platform for MID products:
    • Ubuntu provides two builds for it: Ubuntu Mobile Internet Device Edition for MIDs and Ubuntu Netbook Remix for mini-notes.
  • 10 + 2 things you’ll get with Ubuntu 8.10 “Intrepid Ibex”
    • This is just a certain bloggers thoughts.
    • These come from blueprints on Launchpad, so there is no guarantee that these features will be implemented in the final version.
    • 1. faster login
    • 2. better Flash experience
    • Intrepid will ship improved plugin finder wizard experience, better experience for sites that use the flash detection kit and improved user- experience for selection of available alternatives.

    • 3. 3G networking
    • Title says it all, Intrepid will have built-in support for 3G networking with the new NetworkManager.

    • 4. guest account
    • It is very common to lend someone else a laptop for a quick email check, or having one’s computer play music and be a surf station on a party.

    • 6. Automatic download of printer drivers through the internet
    • The printer setup tool of Ubuntu 8.10 and later will automatically download LSB-packaged printer drivers from the OpenPrinting database.

    • 7. font selector
    • Fontconfig offers a variety of font related settings, which can currently only be modified by hacking a XML file together. Intrepid will have a GUI for this task, taking common settings like font ordering, antialiasing, hinting and embedded bitmaps into account, as those settings vary greatly depending
      on different users’ preferences.

    • 9. installation from USB stick
    • An application will be developed to convert and write Ubuntu CD images to USB disks. In addition, Ubuntu’s existing tools will be modified to better handle installing from a removable disk.

  • Linus is a P.I.M.P – Linus calls the OpenBSD crowd a bunch of masturbating monkeys.

  • 8.04.1 – Release announcement. Some highlights:
    • Firefox has been upgraded to the final 3.0 release
    • The Samba client allows LANMAN authentication again, correcting problems connecting to some NAS and older Windows servers (#209520).

    • While we have fixed a number of audio-related issues, including a scheduler problem that caused audio stuttering under load (#188226), other audio playback problems may still exist, because so far we have been unable to verify a targeted fix that does not cause regressions for other users. We will continue to investigate this  See https://bugs.launchpad.net/bugs/191027 for details.
    • Images updated for Kubuntu, the Kubuntu KDE4 remix, Gobuntu, Xubuntu, and Ubuntu Studio. Mythbuntu to follow soon.
